Adjusting the height of an <iframe> element to match the full height of the document

My code snippet is:

<iframe src="http://www.externalsite.com/" style=""/>

I need to set the height of the iframe to match the total height (X pixels) of www.externalsite.com. Since X is unknown, how can I achieve this using CSS or alternative methods without JavaScript?

Answer №1

Give this code a shot

<body style="margin:0px;padding:0px;overflow:hidden">
<iframe src="http://www.example.com" frameborder="0"   style="overflow:hidden;height:100%;width:100%" height="100%" width="100%"></iframe>
</body>
